When looking at valve-train components, look no farther than S&S.
They have been our go-to source for roller rocker arms, pushrods, etc, for decades now, in our builds from Shovelheads, to 2012 T/C's.
Top quality products, from one of the industry leaders.

SE`s are pretty hard to beat for smaller cam,milder builds as the covers come with the p/rods for around 150.00.for any more aggressive builds,we use S&S or smith bro`s (we use smith bro`s on our nitro bike)
